C bus interface can be configured as

master or slave, which support standard / fast

/ fast plus / high speed mode data transfers.

Max data transfer rate up to 3.4Mbit/s. Clock

stretching is supported.

UART interface can be configured as one full

programmable UART0 or two simple UART0 and

UART1 with CTS / RTS control function only.

Four user timers

watchdog function

with

pre-scaling

and



Support 7 independent PWM channels. Channel

0 and 1 can be configured as PCM 8-bit/16-bit

stereo audio output.
